DISPLAY DEVICE.

Application filed October 17, 1912.

To all whom it may concern Be it known that I, HENRY W. KNAUTZ, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Display Devices, of which the following is a specification.

My invention relates to display devices and more specifically to that class thereof characterized by the employment of detachably' connected cards upon which the articles or matter for display are arranged.

T he object of my invention is the production of a display device, as mentioned, wherein the display cards will be detachably connected in such a manner as to permit of ready detachment so as to facilitate insertion of new cards or interchange of the cards included in the device.

A further object is the production of a display device, as mentioned, which will be of simple and economical construction and hence of low cost to manufacture.

Other objects will appear hereinafter.

lVith these objects in view, the invention consists in the combinations and arrangements of parts hereinafter fully described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which- Figure 1 is a perspective view of a display device embodying my invention showing the same in folded condition, a portion of the device being broken away in order to better illustrate the construction, Fig. 2 is a fragmentary plan View of the flexible body strip included in the construction. Fig. 3 is a transverse section through the device when in folded condition, and Fig. 1 is a plan view of one of the display cards detached.

The preferred form of construction as illustrated in the drawing comprises a flexible elongated body strip 1 formed preferably of fabric. Provided in the strip 1 adjacent the longitudinal edges thereof are spaced elongated slits or openings 2, said openings or slits adjacent the opposite edges of the strip being arranged in pairs or in transverse alinement, as clearly shown in Fig. 2.

Cooperating with the strip 1 is a plurality of separate rectangular cards 3 possessing Specification of Letters Patent.

a certain degree of rigidity, cardboard being preferably used in this connection. Said cards 3 are all of the same dimensions, the width thereof corresponding with that of the strip 1. The lateral edges of each of the cards 3 adjacent one of the transverse edges thereof are formed with notches 1 which result in the formation of tongues 5 adapted for engagement with the slits or openings 2, as clearly shown in Figs. 1 and 2. In attaching the cards, it is necessary, of course, to buckle the same in order to reduce their width sufliciently to permit of engagement of the tongues 5 with the slits 2. When said tongues are in engagement with said slits, the rigidity of the cards will evidently serve to maintain the engagement.

W hen the cards are arranged upon the strip 1, the former will overlap each other when said strip is extended, so as to expose the lower ends of said cards, upon which, when the device is in use, will be arranged the samples for display. When the device is not in use, the strip 1, bending upon transverse lines 6 in a zigzag manner, will permit of collapse or folding of the device to bring the cards in registration with each other, as shown in Figs. 1 and 3. V

Spaced in the strip 1 are transversely extending slots or openings 7 which, when the cards 3 are arranged upon said strip, expose portions of the front sides of the cards adjacent the attached edges thereof. In use, the numbers or other matter referring to the samples carried upon the cards will be placed upon the latter in registration with the openings 7 so that the same may be read by simply moving the cards apart slightly in order to expose said openings, it not being required, with this arrangement, to fully extend the device in order to learn that which is exposed at the openings 7. lhis will be appreciated by those familiar with devices of this character, as of great advantage.

The device is simple and economical of construction and will be found efficient in use.

\Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details as set forth, but desire to avail myself of such variations and modifications as come Within the scope of the appended claims. 7

Having described my invention, What I claim as new and desire to secure by Letters Patent is:

1. A display device comprising an elon- Copies of this patent may be obtalnedfor five cents each. by addressing the Commissioner Washington,

7 2. A display device comprising an elongated fiexible strip; and a plurality of separate cards secured to said strip, there being an opening in said strip positioned opposite a portion of each of said cards when said strip is folded Zigzag, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
